Implement begin- and ending timeouts compatibel with Girs and HarcHardware

[bengtmartensson]

It the lirc hardware does not support it, use read timeouts with poll(2) or select(2). Use LIRC_SET_REC_TIMEOUT and LIRC_SET_REC_TIMEOUT_REPORTS.

Note: Girs and HardHardware as well as poll uses values in milliseconds, Lirc microseconds.

All lirc kernel driver should report timeouts. If you find one that does not, please report a bug and I will fix it.

Thanx for the advice. Now it only remains to implement it ;-).
